Radar qib sensors yog ib qho kev ntsuas ntsuas txuas ntxiv hauv cov tso tsheb hlau luam thiab silos thoob plaws kev lag luam xws li tshuaj lom neeg, kev kho dej, khoom noj, mining thiab lwm yam. Lawv muab kev ntsuas qhov tseeb, tsis muaj kev sib cuag tsis hais qhov siab, qhov kub thiab txias, vapor, lossis plua plav. Txawm li cas los xij, kev teeb tsa kom raug yog qhov tseem ceeb rau kev ua kom pom kev ua haujlwm zoo. Qhov chaw tsis raug yuav ua rau muaj teeb meem cuam tshuam, tsis muaj suab nrov, thiab nyeem tsis raug.
Hauv qab no yog cov lus qhia ua tiav ntawm yuav ua li cas rau nruab radar qib transmitters, suav nrog kev ua yuam kev ntau dhau los zam thiab kev coj ua zoo tshaj plaws rau ntau hom tank.
Vim li cas Radar Installation Txoj Haujlwm Tseem Ceeb
Ib qho ntawm feem ntau yuam kev uas peb cov neeg muas zaub ntsib yog tso lubradar qib sensorncaj qha nyob rau hauv nruab nrab ntawm ib tug arched los yog domed tank, uas yog tiag tiag ib tug ntawm qhov phem tshaj qhov chaw rau nruab lub sensor.
Yog vim li cas? Thaum radar pulses raug tso tawm los ntawm qhov chaw ntawm lub tank domed, lub teeb pom kev zoo los ntawm cov kua saum npoo kuj tau rov qab mus rau lub ru tsev tank. Ntawm lub apex ntawm lub dome, cov echoes tuaj yeem mloog zoo thiab tsim muaj ntau qhov kev xav. Cov "dag echoes" no tuaj yeem muaj zog dua li qhov tseeb ntawm cov kua theem teeb liab, ua rau tsis meej pem lub transmitter thiab ua rau kev ntsuas tsis raug.
Yog li ntawd, tsis txhob nruab radar qib sensors nyob rau hauv nruab nrab ntawm round lossis arched tank saum. Hloov chaw, xaiv qhov chaw offset los ntawm qhov chaw, qhov uas qhov kev pheej hmoo ntawm cov teeb liab cuam tshuam tsawg.
Xaiv qhov chaw teeb tsa raug
1. Flat-Topped Conical Tanks
Rau cov tso tsheb hlau luam nrog lub ru tsev tiaj tus thiab conical hauv qab, kev txhim kho lub radar nyob rau hauv qhov chaw yog qhov tsim nyog. Qhov kev teeb tsa no tso cai rau lub radar beam kom ncav cuag qhov qis tshaj plaws ntawm lub khob hliav qab, muab cov kev nyeem kom raug thoob plaws lub tank tag nrho. Txawm li cas los xij, rau cov khoom siv, yog tias pawg tsis sib xws, ncha poob tuaj yeem tshwm sim. Nyob rau hauv cov ntaub ntawv no, siv ib tug swiveling flange los yog universal sib koom ua ke los kho lub radar lub kaum sab xis, kom lub beam aligns perpendicularly nrog cov khoom nto.
2. Domed lossis Rounded Tanks
Zam qhov chaw nruab nrab. Qhov chaw pom zoo yog 1/6 rau 1/4 ntawm lub tank txoj kab uas hla ntawm phab ntsa. Qhov chaw no txo qis qhov kev pheej hmoo ntawm ntau lub suab nrov ntawm lub dome apex. Tsis tas li ntawd, tswj qhov kev ncua deb ntawm tsawg kawg yog 1/10 ntawm lub tank qhov siab ntawm phab ntsa kom tsis txhob muaj kev cuam tshuam ntawm phab ntsa.
General Installation Guidelines for Radar Level Transmitters
Txhawm rau xyuas kom meej thiab txhim khu kev ntsuas, xav txog cov lus qhia hauv qab no thaum lub sijhawm teeb tsa:
Kev ncua deb ntawm Tank Phab Ntsa: Khaws tsawg kawg 1/10 ntawm lub tank qhov siab thiab zoo dua nruab lub radar ntawm 1/6 txog 1/4 ntawm lub tank inch ntawm phab ntsa.
Flange Alignment: Lub flange qhov kev sib dhos yuav tsum taw tes rau ntawm phab ntsa tank. Xyuas kom lub flange mounted nyob rau hauv ± 0.5℃los ntawm kab rov tav.
Kav hlau txais xov Positioning: Lub kav hlau txais xov lub taub yuav tsum yog tsawg kawg 10 hli hauv qab ntawm lub tank nozzle. Rau horn antennas, lub horn yuav tsum txuas mus rau hauv qab nozzle los yog ib qho kev sib txuas cov yeeb nkab kom tsis txhob muaj teeb liab cuam tshuam.
Tsis txhob cuam tshuam qhov chaw: Tsis txhob teeb tsa lub radar ncaj qha rau saum cov inlets, qhov hluav taws xob, cov agitators, ntaiv, lossis cov qauv sab hauv. Yog tias tsis tuaj yeem zam tau, siv echo mapping lossis qhov tsis tseeb echo suppression muaj nuj nqi thaum teeb tsa.
Obstacle Reflection: Yog tias lub tank muaj cov txheej txheem sab hauv xws li cov kav dej lossis cov kev txhawb nqa, xav txog kev txhim kho lub teeb pom kev zoo los coj cov nqaj radar thiab tiv thaiv cov suab tsis tseeb.
Cov Khoom Siv Khoom Siv Khoom: Hauv cov khoom siv ntau nrog cov kaum sab xis, xyuas kom cov ntsiab lus radar beam ntawm cov khoom nto. Misalignment tej zaum yuav ua rau cov teeb liab tsis muaj zog lossis poob ntawm kev ntsuas. Siv cov khoom siv kho kom haum kho kom haum kom zoo - kho qhov nqaj kev taw qhia.
Cov lus qhia tshwj xeeb rau Tank Hom
Me me -Diameter Tanks: Thaum qhov chaw muaj tsawg, cia kom deb li deb tau los ntawm phab ntsa. Yog hais tias echoes tseem muaj teeb meem, siv lub radar lub ncha suppression muaj nuj nqi khaws cia thiab tsis quav ntsej cov teeb liab tsis tseeb.
Corrosive lossis Adhesive Media: Xaiv cov qauv radar nrog PTFE-coated antennas lossis tsis yog- cov ntaub ntawv lo.
Kev Tiv Thaiv Kev Tshaj Tawm: Teem thaj tsam tuag lossis tsis yog- ntsuas thaj tsam sab saud me ntsis siab tshaj qhov sau siab tshaj plaws. Qhov no tsis tuaj yeem ua haujlwm raws li lub tswb nrov.
Radar hom qib sensor yog cov cuab yeej muaj zog rau qhov tseeb, tiag - lub sijhawm saib xyuas theem tab sis tsuas yog thaum ntsia kom raug. Kev nkag siab txog yuav ua li cas lub tank zoo, cov qauv sab hauv, thiab txoj kev teeb liab cuam tshuam rau kev ua haujlwm yog qhov tseem ceeb kom tsis txhob ntsuas qhov yuam kev.
